Patent CA-2032147-A1 (CA)
Title: Rotor unit for a postagemeter machine
Inventor: LINDENMULLER JOHANN
IPC: B41K3/12
Filed: 1990-06-21
Abstract: ABSTRACT     A rotor unit having a rotor cylinder, which is attached to a shaft and rotates in an external bearing.  Inside is a setting motor which drives a first combination gear in two directions of rotation via its setting shaft and a pinion. The combination gear is mounted on a disk and a bearing disk in a free-wheeling bearing and engages with a second combination gear.  In one direction of rotation, the free-wheeling bearing locks the combination gear, so that the gear is carried along by the pinion in a fixed position together with the disk.  In this way the second combination gear engages serially with one intermediate gear at a time, with each engagement being exactly positioned by means of a ball groove.  In the other direction of rotation, the motor turns the respective numeral wheel via the aforementioned gears, thereby setting, for example, one numeral of the postage-meter machine's postage value stamp.  As a result of the motor alternately rotating in the two directions, all numerals of the value stamp, the date stamp and other stamps can be automatically set.  The motor receives its commands via rubbing contacts from a control unit located outside the rotor cylinder.

Inventor: DEFRANK MICHAEL P
IPC: G01K1/08
Filed: 1991-03-07
Abstract: The thermal isolation apparatus for the protruding probe of a biomedical thermometer includes an insulative air gap and a heat sink disposed between the surface of the probe and the optical path through the probe. The heat sink surrounds the optical path, such as a waveguide, and acts to evenly distribute any heat along the entire length of the waveguide to avoid temperature variations. Additionally, the heat sink has sufficient mass for high heat capacity and may slow the progress of any heat from reaching or leaving the waveguide until after the measurement by the biomedical instrument has been completed. Disposed over the heat sink is a boot which forms the closed air space between the heat sink and the outer probe surface. The air gap combined with the heat sink provide relative thermal isolation of the optical path through the probe and provide relative thermal isolation of the target anatomy from the temperature of the probe.

Inventor: IKEMATSU HIDEKI
IPC: G03G15/20
Filed: 1991-06-19
Abstract: A fixing unit of an electro-photographic apparatus comprises:  a heat roller installed on a frame, for fixing a toner image on a sheet; a pressure roller for pinching the sheet with the heat roller; a separator contacting the heat roller, for separating the sheet from the heat roller; a cleaning wiper contacting the heat roller, for cleaning the heat roller; and a sub-frame carrying the pressure roller, the separator and the cleaning wiper.  The sub-frame is rotatable about an axle which is installed on the frame, in parallel to the heat roller.  The pressure roller, the separator and the cleaning wiper are released all together from the heat roller when the sub-frame is opened by being rotated around the axle.          In the thus-opened state, any jammed sheet can be easily taken out by an operator as the jammed sheet is exposed    in a wide space and the sheet is merely sticking to heat roller without being undesirably snagged by the separator or by the cleaning wiper.  Moreover, the easy sheet-removal operation prevents the operator's fingers from being burnt by touching the hot heat roller.
